Exploring microbial oil from oleaginous actinobacteria Streptomyces fradiae for biodiesel application

Abstract

Streptomyces fradiae is a commonly used microorganism for designing the targeted antibiotic drugs. It has many medicinal properties, due to the presence of antibiotics, antioxidants and other bioactive compounds. The lipid producing efficiency of Streptomyces fradiae in biodiesel feedstock production is explored in this study, the fermentation of Streptomyces fradiae and Aspergillus fumigatus was successful using waste rice wash water (RWW). In this communication, the efficiency of most widely used algae Aspergillus fumigatus in biodiesel feedstock production is compared with Streptomyces fradiae JJ1 MK733985.1. The result showed that Streptomyces fradiae grown in RWW produced a lipid content of 15% from biomass and, the microbial oil yield was 7.5g/L. Whereas, the results of Aspergillus fumigatus showed a lipid content of 12% from biomass and the microbial oil yield was 4.8g/L. According to the findings, Streptomyces fradiae was comparatively more beneficial than Aspergillus fumigatus in microbial oil production.
